identified by a numbering system from 1 through 70. P. wingei from the Campoma region are also known as the Campoma guppy. Cumana Poecilia wingei Poecilia wingei from the Cumana region were originally known as Endler's guppy. Endler's livebearer, originally discovered in 1975 by John Endler and are found in Laguna Patos and in the lagoon's connected streams and canals, was actually a micropoecilia species that is believed to be extinct. In 2009 the Schories et al. publication broadened the definition of P. Wingei to include Endler's livebearer. Most P. Wingei from the Cumana region found in the hobby today are descended from those collected by Armando Pau and were line bred and distributed to hobbyists by Adrian Hernandez (AdrianHD). P. Wingei from the Cumana region are also known as the Cumana guppy. El Tigre Poecilia wingei El Tigre are Poecilia wingei collected from the El Tigre stream in the Campoma region of Venezuela. The El Tigre stream is not connected to Laguna Campoma so the El Tigre belong to their own distinct population. All El Tigre found in the hobby today are descended from those collected by Phil Voisin (Philderodez). Staeck Endler (hybrid) The Staeck guppy was collected by Dr. Wolfgang Staeck in a creek around Laguna de los Patos in Cumana in 2004. Karen Koomans obtained a Staeck guppy male from the Hamburg University and identified it as pure Poecilia reticulata. Karen Koomans crossed this Staeck guppy male with a 'Yellow Top Sword' Endler female. She introduced the new line to the hobby as the 'Hamburg hybrid Endler strain'. Japan blue Endler (hybrid) The original japan blue wild type guppy was a Poecilia reticulata collected from Lac du Rorata. Lac du Rorota is a reservoir in French Guiana. Karen Koomans received a single male japan blue guppy and crossed it with Cumana Endler females to preserve the strain. Karen Koomans introduced this strain to the hobby as the 'Japan blue wild type guppy'. Hybrids Endlers (P. wingei) can be crossed with guppy species (P. reticulata, P. obscura), and the hybrid offspring will be fertile. This is considered to dilute the gene pool and therefore is avoided by fish breeders who wish to maintain pure strains. Avid hobbyists maintain registry records to ensure their Endlers are purebred; undocumented fish sold in pet stores as Endler's livebearers are assumed to have some degree of guppy hybridization. In addition, as P.
